I need some help! - Automatic Voltage Regulator?

This was originally posted on APC forums on 1/14/2012

I need some help!

I am working with a large senior housing building.
I installed a WIFI system for the residents.

My Problem is the WIFI power supplies ( 120/4amp/5vdc )
for the WIFI routers are burning out every 6-8 months
( I have tried different models )

I have tested the outlet voltage and it varies from 122-125v ac
I believe that because the voltage is to high it is causing the
transformers to burn out quickly - I need a fix for this!

I am looking at ..

APC Line-R 1200VA
APC LE600 Line-R 600VA
Or is there something better ?

I think if I am not mistaken that BOTH vers of the Voltage Regulator
only work to REDUCE voltage when the AC voltage reaches 127v-ac

I need something that keeps the AC voltage 118v120v !!!!
Is there a solution to my problem ?
